maxwellhill posted:Corsi boxes. For the use case where left running in a room with several people, they're supposed to keep them safe from one another. I'm wondering how we square that with those visualizations/simulations that showed how exhalations actually travel in rooms (generally upward toward the ceiling quite fast, spreading from there). Corsi boxes use furnace filters. They're not single pass purifiers anyway so you're preventing viral aerosols from building up over time, not preventing a single particle from making it across the room once. The latter is like a clean room use-case where you need extremely high cfm hepa filters or vertical evacuation fans or both.

Salt Fish posted:Partical counters are cheap and fun to play with. They will convince you about how good corsi cubes are. It's honestly way overkill in a normal residential space, but there aren't really downsides. I want one of those things for measuring the fit factor of masks, but they're horribly expensive, or random used ones on ebay that who knows how well they work anymore, and presumably cannot be calibrated.

Rescue Toaster posted:I want one of those things for measuring the fit factor of masks, but they're horribly expensive, or random used ones on ebay that who knows how well they work anymore, and presumably cannot be calibrated. That’s a portacount. It’s a condensing particle counter (CPC). You can get them for maybe $800 on ebay. They measure from 0.02 to 1.0 microns. Respiratory aerosols are about 0.3-3.0 micron. Cheap particle counters are only useful 0.3 or 0.5 up to 1.0 even though they report lots of other sizes. The numbers they report for those other sizes are crap. edit: Also the cheap particle counters typically only work correctly at certain concentration ranges, which are not necessarily documented. Anyway, get something with a PMS5003 or an SPS30 and time average the PM1.0 at 60s to end up with decent data. It will show you how fast the particles drop and it is possible to calculate the CADR of an air cleaner. edit: Aaron Collins is making an opencpc, which will probably be cheaper than a new portacount but less cheap than a used one.

"There are no negative effects" lmao I play lovely online shooters and the other day two guys on voice chat just started bullshitting about how they've both had Covid six or more times and how they have no choice because of their jobs and it just is what it is, being sick all the time is their only choice if they want to pay their rent. cool!

I had to use tram two days ago and forgot my masks home because I am a big noob. There were quite a few runny noses around, and naturally already yesterday I started feeling a bit unwell. Today I have chills, and still feeling worse. It is completely possible that my immune system manages to fight the bugs off and I won't get really sick, but still. Why even one mistake always has to end up like this. How do regular people manage? Perhaps their immune systems aren't as deep in debt as mine?

In a recent NYT piece,quote:And then one day, something had changed. “People started looking me in the eye, and I knew they were smiling although I couldn’t see the smile,” she said, gesturing to indicate the masks everyone wore at the time. Setting is an American university. Guess when “the time” when everyone wore masks was. spring 2022

So, my sister helped run the phase 1/3 study for the first Moderna vaccine. She just found out this morning that this next-gen study got pushed from this spring to this fall, which sucks, but I didn't know about it in the first place. samRNA sounds interesting, but I don't get why making other parts of the virus besides spike protein will help, as infection itself doesn't confer lasting immunity. Also, in my head now I will always think of it as "something awful mRNA"

This is a big part of the hopelessness for me as well. SARS-CoV-2 evades immunity so I'm not sure how a vaccine alone is supposed to help. It doesn't seem like a good plan to me.

He bought one of those medical ultrasound machine and placed it in his home and have a specialist come in weekly and check his organ and all that. He definitely know because he's been seeing the damage happening over time. Honestly he could legit be one of the best source for in depth study for PASC since he has all that poo poo load of data on weekly/daily basis. Far better than a spreadsheet

Pertussis aka whooping cough genuinely sucks so bad. Did you know that adults need to get a Tdap booster every 10 years? I had no clue, and then I got whooping cough. Extremely do not recommend, which is why I now constantly post PSAs telling goons to get Tdap boostered. Vaxmaxxing
